一、前言

有时我们会遇到这样的需求：将信息标注到地图上，然后将包含地图和信息的图片展示在页面上或者导出到Word中。这样我们就需要用到高德的静态地图API。

静态地图服务通过返回一张地图图片响应HTTP请求，使用户能够将高德地图以图片形式嵌入自己的网页中。用户可以指定请求的地图位置、图片大小、以及在地图上添加覆盖物，如标签、标注、折线、多边形。

二、静态地图样例

1.单个点标注
https://restapi.amap.com/v3/staticmap?location=116.481485,39.990464&zoom=10&size=750*300&markers=mid,,A:116.481485,39.990464&key=自己申请的Key值2.多个点标注
https://restapi.amap.com/v3/staticmap?markers=mid,0xFF0000,A:116.37359,39.92437;116.47359,39.92437&key=自己申请的Key值3.自定义点标注
https://restapi.amap.com/v3/staticmap?markers=-1,https://a.amap.com/jsapi_demos/static/demo-center/icons/poi-marker-default.png,0:116.37359,39.92437&key=自己申请的Key值4.标签
https://restapi.amap.com/v3/staticmap?location=116.48482,39.94858&zoom=10&size=400*400&labels=朝阳公园,2,0,16,0xFFFFFF,0x008000:116.48482,39.94858&key=自己申请的Key值5.点标注和标签
https://restapi.amap.com/v3/staticmap?location=112.525878,37.811284&zoom=14&size=400*300&scale=2&markers=-1,https://cache.amap.com/lbs/static/cuntom_marker1.png,0:112.525878,37.811284&labels=测速人,2,0,16,0xFFFFFF,0x008000:112.525878,37.811284&key=自己申请的Key值6.线
https://restapi.amap.com/v3/staticmap?zoom=15&size=500*500&paths=10,0x0000ff,1,,:116.31604,39.96491;116.320816,39.966606;116.321785,39.966827;116.32361,39.966957&key=自己申请的Key值7.多边形
https://restapi.amap.com/v3/staticmap?zoom=15&size=500*500&paths=2,0xFFFF00,0.5,0xFFFF00,0.5:116.31604,39.96491;116.320816,39.966606;116.321785,39.966827;116.32361,39.966957;116.31604,39.96491&key=自己申请的Key值

没有Key值的可以注册一个高德开发者账号申请Key值

三、参数

参数名称	含义	规则说明	是否必填	默认值
key	用户唯一标识	用户在高德地图官网申请	必填	无
location	地图中心点	中心点坐标。规则：经度和纬度用","分隔经纬度小数点后不得超过6位。	部分条件必填	无
zoom	地图级别	地图缩放级别:[1,17]	必填	无
size	地图大小	图片宽度图片高度。最大值为10241024	可选	400*400
scale	普通/高清	1:返回普通图； 2:调用高清图，图片高度和宽度都增加一倍，zoom也增加一倍（当zoom为最大值时，zoom不再改变）。	可选	1
markers	标注	使用规则见markers详细说明，标注最大数10个	可选	无
labels	标签	使用规则见labels详细说明，标签最大数10个	可选	无
paths	折线	使用规则见paths详细说明，折线和多边形最大数4个	可选	无
traffic	交通路况标识	底图是否展现实时路况。可选值： 0，不展现；1，展现。	可选	0
sig	数字签名	数字签名认证用户必填	可选	无

高德静态地图API

四、页面展示

现在我们设计好了图片，需要把图片展示到页面上。

思路是获取到高德接口返回的输入流将其转换为BASE64编码的字符串。

    String url = "https://restapi.amap.com/v3/staticmap?location=112.525878,37.811284&zoom=14&size=400*300&scale=2&markers=-1,https://cache.amap.com/lbs/static/cuntom_marker1.png,0:112.525878,37.811284&labels=测速人,2,0,16,0xFFFFFF,0x008000:112.525878,37.811284&key=自己申请的Key值";String base64 = getMapBase64(url);String urlBase64 = "data:image/png;base64," + base64;public String getMapBase64(String requestUrl) {try {URL url = new URL(requestUrl);URLConnection urlCon = url.openConnection();InputStream is = urlCon.getInputStream();byte[] buffer=new byte[1024];int len=0;ByteArrayOutputStream bos=new ByteArrayOutputStream();while((len=is.read(buffer))!=-1){bos.write(buffer,0,len);}bos.flush();BASE64Encoder encoder = new BASE64Encoder();return encoder.encode(bos.toByteArray());//返回Base64编码过的字节数组字符串} catch (IOException e) {e.printStackTrace();return "error";}}

将得到的urlBase64传入img的src

五、导出Word

将id=wordMain的标签中的内容导出成Word

1.导入
<script src="FileSaver.js"></script>
<script src="jquery.wordexport.js"></script>2.调用其中方法
$('#wordMain').wordExport('Word月报');
#wordMain：需要导出模块的id
Word月报：导出之后的名字3.导出的word可以保留样式，但是样式需要写到#wordMain的里面，写在外面或者#wordMain上面都不会展示
